To all whom it may concern.-

Be it known that I, EDWARD F. GRANDY, a citizen of the United States,residing at Boston, in the county of Suifolk and State of Massachusetts,have invented certain new and useful Improvements in Machines forLasting Boots and Shoes, of which the following is. a full, clear, andexact description, reference being had to the accompanying drawings,forming a part of this specification, in explaining its nature.

This invention consists of improvements upon those described and shownin prior Letters Patent granted me as joint inventor with others, datedJune 28, 1887, and numbered, respectively, 365,504: and 365,505, and itrelates to various details of construction to be hereinafter described.

In the drawings, Figure 1 is a plan view of the heel-lasting head,showing the band embracing the heel. Fig. 2 is a plan view of the samehead with the lasting-plates and operating mechanism removed, showingthe band open. Fig. 3 is a side elevation of the head and its support,showing the relation of the head to the jack-post. Fig. 4 is a frontelevation of part of Fig. 3. Fig. 5 shows a portion of the j ack-postand its locking mechanism. Fig. 6 is a cross-section of Fig. 5,sl1owingthe relation of the rack and pinion and the ratchets and pawls. Fig. 7shows the treadles for operating the pawls.

Similar letters refer to similar parts th ro u ghout the several views.

In the improvements shown in said prior Patent No. 365,50e, the band wasdrawn around the heel or toe in sections, and one of the objects of thisinvention is to provide means whereby the band may be drawnsimultaneously around both sides of the heel or toe of a boot or shoeand an adjustment to equalize the strain with reference to right andleft lasts.

Another object of my said invention is to hold the jack-post more firmlyagainst the downward pressure than heretofore, and at the same time togive it a more minute adjust ment and greater stability in its sleeve.

D represents the heel band or strap, Figs.

1 and 2, to be composed of metal and leather and to be secured at itscenter under the downhold a to the head A at a a. Both sides of thisband are simultaneously pressed or drawn around the sides of the heel bythe bell-crank levers (1 cl, operated by the sliding bars d 01 againstthe force of the springs d d, and linked to the bell-crank levers (Z dby the connecting-links d (1 levers d d are operated by the foot-treadleE, Fig. 4, through the connection E, to which are jointed thedrawing-rods e e. These rods 6 e pass through lugs d (1 and by actingagainst the force of the springs e 6' cause both sides of the band toembrace the quarter or toe of a boot or shoe, provision being made bythe thumb-screw nuts e e to regulate the intensity with which the bandembraces the shoe, the springs e e yielding with reference to each otherto accommodate the band to the variations in size of lasts and also tothe variations in shape of right and left lasts.

By inspection of Letters Patent No. 365,505 it will appear that afterthe lasting process is finished, in order to remove the last from themachine, the foot-treadle Pis pressed down, thereby allowing all partsof the machine to These bell-crank resume their normal positions readyfor another last to be put in position on the jackpost.

In order to prevent'injury to the levers d (P, rebound-springs at d dare placed beneath the lugs 61 d and their positions are adjusted by thecollars and set-screws d cl".

In said Patent No. 365,505 the jack-post is shown supported againstdownward pressure by a ratchet out directly thereon and pawls engagingtherewith; but in my present invention a rack is out directly upon'thejackeach side thereof, and to engage with the teeth of said ratchets Ihave arranged the pawls a a", of sufficient strength to give the desiredstability to the j ack-post, and in order to give increased range ofadjustment to the jack-post I make one pawl one-half of a ratchet-toothlarger than the other, both being hung upon a common center. Fixed uponthis shaft are the pawl-lifters a a operated by the lever a Fig. 3, bymeans of the connecting-rod a, Fig. 3, attached to a crank a, so thatthe depression of the lever P will raise the pawls a a clear of theteeth of the ratchets a a and allow freedom of motion to the jack-postand the parts connected therewith.

' 7 What I claim as my invention, and desire to secure by LettersPatent, is-

1. In a lasting-machine, the combination,

with lasting devices, of a jack-post movable in its support, and aspring for moving it upward in relation thereto, with a rack on the backof said jack-post and a pinion which engages with said rack and preventssaid jack-post from turning in its sleeve, substantially as and for thepurpose shown and described.

2. In a lasting-machine, the combination, with lasting devices, of therack a and pinion a with the ratchet-wheels a. and a the retaining-pawlsa and a and lifting mechanism for said pawls, substantially as and forthe purpose shown and described. I

3. In a lasting-machine, the combination, with lasting devices, of thefoot-treadle E, the connection-rods e e,'each provided with a collar andspring and springs for governing or equalizing the pressure given by theband on the counter or toe, substantially as and for the purpose shownand described.

4. In a lasting-machine, the combination, of the spring e, thethumb-screw nuts 0 and the rod e, arranged and operating in the mannerand for the purpose as shown and described. V
